Wolf Skull Cave

If you're like me and like to use Alchemy, this place has some nice assortment of mushrooms. As you walk you'll find the usual Draugr but also quite a few wizards. I recommend bringing along a companion if you are low level. Mostly Necromancers, so prepare for the undead. As you travel you will come to a pit, which you drop down into and find the door that takes you to the Wolf Skull Ruins. Once there enjoy the beautiful graphics and swirly blue energies. There are many stairs that you have to use to get higher into the cavern. It's pretty straight forward and once you clear the place you return to Solitude and Falk. Since you can't go back up the pit, you'll need to find the other way out. At the top of the tower is a lever, pull it to drop the bridge. It's a bit dark so don't miss the treasure chest just across the bridge. I found some gold, a petty soul gem w/ soul, Waterbreathing spell tome, silver necklace (60 gold value) and a Ring of Recharging which regenerated my Magicka 40% faster. Head down the stairs to a door that leads back to the WS Cave. Drop off the ledge and find Falk again at the Blue Palace.
